Ground penetrating radar, GPR, is a high resolution geophysical method,
which is based on the propagation of high frequency electromagnetic waves. The
GPR method images structures in the ground that are related to changes in
dielectric properties. In sediments, water content primarily causes the changes in
dielectric properties. Therefore GPR can be used to estimate underground watertable.
In this study a GPR system has been used successfully to produce a
continuous profile of the water table on the (Said Abdullah bin Al-Hassan Shrine)
as a study area, which is located in Al-Yousifyah region to the south of Baghdad.
Geotechnical field test to underground water determination by the drilling method
commonly used to comparing the results between geotechnical field test and GPR
test. Thus, GPR has proven to be an effective detection method for underground
water level, and can serve as reference for future applications.
